12 Dismantling and Disposal
12.1 Dismantling
To dismantle a Multi-DENCO unit, proceed as follows:
• Stop the unit as per chapter 9.2.5
• Disable electrical power to the unit as per chapter 9.2.6
• Ensure that the power supply cannot be 're-activated' by interlocking the supply/
supplies at the main power board and removing any fuses
• Make sure to close all valves inside the side section and base stand while using
DMW/DMP before disconnection with main unit.
• Humidifier
• Turn off the water feed to the humidifier (if fitted)
• Remove the humidifier connection to the condensate drain
• Ensure the humidifier bottle is suitably sealed or appropriately drained
• Water Circuits
• Close off/shut the valve on any water circuits, hot or cold (if fitted)
• Drain the water/water mixture from the circuit
• Disconnect the water connections and ensure no further fluid is leaking
• Refrigeration circuits
• A specialist refrigeration engineer should be employed to recover and safely
dispose of the refrigerant gas and any associated oils and glycols prior to cutting
and capping off the refrigerant pipework
• A qualified electrical contractor should be employed to remove/recover the
main(s) and any interconnecting cabling
• Once mechanically and electrically separated from the system, attend to releasing
the Multi-DENCO unit from any fixings to the floor or other sub-structures
• Prepare the unit for handling and transportation as per chapter 4
• Ensure all incoming electrical connections are isolated and cannot be
inadvertently energised.
• Inverter technology and rotating fans required at least 5 minutes from electrically
isolating the unit before any doors or panels can be removed.
• Use earth and short-circuit and cover or isolate any neighbouring live parts.
• Recover all refrigerant or cooling medium and use inert medium (e.g. Oxygen
Free Nitrogen) to equalise the system pressure to meet ambient air pressure.
